CORN-SHOCKING MACHINE.

Specification of Letters Patent.

Patented Sept. 26, 1905.

Application filed June 17,1906. Serial No. 266,665.

To all whmn it may concern.-

Be it known that I, DANIEL W. Sirnrna citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Corn-Shocking Machines,of which the following is a specification, reference being had to theaccompanying drawings, forming a part thereof.

My invention relates to corn-shocking machines of that class having acutting apparatus and a rotatable platform in rear thereof upon whichthe cut stalks are formed into a shock as they are received from thecutting mechanism, the shock-forming means comprising compressingspring-arms mounted upon vertically-disposed rotatable posts arranged atopposite sides of the rotatable platform; and it consists in improvedmeans for locking said rotatable posts in operative position and forsimultaneously rotating said posts to release the pressure of thecompressing-springs and unshipping the clutch mechanism forming part ofthe power-transmitting means connecting the source of power with therotatable platform, the objects of the invention being to provide amechanism for controlling said parts that will be more positive in itsaction and also one that will automatically arrest the rotatablemovement of the platform when the compression-springs are releasedpreparatory to depositing the shock upon the ground. I attain theseobjects by the mechanism illustrated in the accompanying drawings, inwhich Figure 1 is a plan view of a part of a cornshocking machineembodying my invention. Fig. 2 is a sectional detail of the gearconnection and clutch mechanism connected with the rotatable platform.Figs. 3 and 4 are details of the locking means connected with thecompressing-spring standards, and Fig. 5 represents a portion of one ofthe rotating standards with hand-lever attached thereto.

Similar characters refer to similar parts throughout the several views.

1 represents the wheel-frame of the machine; 2, the cutting apparatus;3, a bearingplate secured to the wheel-frame and adapted to support arotatable platform 4. (Shown only in part in Fig. 2.)

5 is a cross-shaft suitably mounted upon the wheel-frame deriving motionfrom the source of power in a well-known way and transmitting it to theother operative parts of the machine, including the rotatable platform,which derives its motion therefrom by means of the shaft 6 andgear-wheels 7, 8, and 9 in a well-known way. It has been the usualpractice in this class of machines to have the shock-receiving platformrotate continuously when the cutting apparatus and other parts werebeing operated. This has been found objectionable, particularly whenmeans for hoisting the shock have been connected with thepower-transmitting means, the rotatable platform requiring considerablepower to give it motion,- which power is utilized to raise the shockwhen the movement of the rotatable platform is arrested as by myinvention. To attain this object, I provide the shaft 6 with a commonform of clutch mechanism comprising a movable clutch member 10, adaptedto engage with the gear-wheel 7, that meshes with a gear surface 11,secured to the rotatable platform 4. The clutch member 10 is moved toengage with the gear-wheel by means of the coiled spring 12, operativebetween a portion 13 on the movable clutch member and a pin 14 throughthe shaft 6. Secured to the part 10 is a part 15, having a groove 16,and engaging therewith is one arm 17 of a bellcrank-lever 18, pivotallymounted upon the wheel-frame of the machine, the opposite end of whichengages with a stop block 19, secured to a reciprocating bar 20,pivotally connected at one end to a lever 21, secured to a rotatingstandard 22, to which are attached compressing spring-arms 23 upon oneside of the machine, the opposite end of said reciprocating bar beingprovided with a toothed rack 24, that meshes with a pinion 25, securedto a rotating standard 26, mounted upon the opposite side of the machineand to which are secured compressing-springs 27. A hand-lever 28 issecured to the rotating standard 22 for the purpose of returning it tooperative position with the compressingsprings in position to receivethe incoming stalks. The reciprocating bar is provided springsurrounding the pivot and operative between the lever and a fixed partof the frame to hold the latch-piece in contact with the end of thereciprocating bar. I'Vhen the shock is being formed, thecompressingsprings are gradually forced outward until they assume aposition approximately eoncentrie with the periphery of the rotatableplatform, the standards 22- and 26 being prevented from rotating by thelocking means already described. When the shock has been completed andready to be deposited upon the ground, the operator by means of thehand-lever 33 releases the latch-piece 32 from contact with thereciprocating bar, and the reactionary force of the spring-compressingarms will immediately rotate the standards, and thereby move the bar 20,and the stop-block 19, coming in contact with the shipping-lever 1S,disengages the clutch mechanism and the rotatable movement of theplatform is arrested until by means of the hand-lever 28 the standardsand compressingsprings are again adjusted to operative positions.

What I claim, and desire to secure by Letters Patent, is

1. In a corn-shocking machine, the combination of a shock-formingplatform, rotatable standards mounted upon opposite sides thereof,compressing-springs secured to said standards, and means forsimultaneously rotating said standards comprising a lever secured to onestandard, a pinion secured to the opposite standard, a reciprocatii'igbar having a toothed rack at one end engaging with said pinion andhaving pivotal connection at its opposite end with said lever.

2. In a corn-shocking machine, the combination of a shock-formingplatform, rotatable standards mounted upon opposite sides thereof,eompressing-springs secured to said standards, and means forsimultaneously rotating said standards comprising a lever secured to onestandard, a pinion secured, to the opposite standard, a reciprocatingbar having a toothed rack at one end engaging with said pinion andhaving pivotal connection at .its opposite end with said lever, and apivotally-mounted latch-piece adapted to lock said bar at eitherextremity of its movement.
